Sheen was fired in March after going on a public rant against his then-bosses, to be replaced two months later by Ashton Kutcher, who made his debut as heartbroken Internet billionaire Walden Schmidt on Monday's episode.

Viewers immediately took to Twitter to share their thoughts on the episode, with mixed reactions. Some opined that the show isn't the same without Sheen, while others were happy to see Kutcher join the cast.
